I've got 4 in mine, also have a volt meter in the old air vent at the end of the dash on the driver side.
The samurai clocks won't fit so you'll have a bit of fun with the wiring, you'll also need the pipe work from the heater for the demisters, if you can get a Spanish dash it has a rev counter, jap ones don't.
Basically you'll want to find a donor and pull everything dash related, just in case there's bits you need, just getting the main dash won't be enough, I'm not 100% sure if the support bar is the same either, not sure why it would need to be different though.
I want to put the even earlier metal dash in my Lwb samurai.
